Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor ventilation system for a building, which can naturally ventilate a room in an optimum state regardless of the wind direction and speed.

[0002]

2. Description of the Related Art As a method of naturally ventilating a room in a building without using forced ventilation, it is common to appropriately open and close a ventilation port or a window provided on an outer wall.

[0003]

However, the efficiency of natural ventilation depends on the wind direction, and it is necessary not only to take measures against strong winds, but also the complexity of artificial work such as the time and effort required to open and close ventilation openings and windows. In a general house, this kind of troublesomeness is not a problem, but when trying to naturally ventilate the interior of the office building, the windows must be opened and closed manually, and If not, natural ventilation cannot be desired. In addition, even if the windows are opened, the ventilation volume differs between the upwind room and the leeward room, and even in the same room, there are many inconveniences such as strong wind blowing around the window and scattering of documents. I had no choice but to rely on forced ventilation using equipment.

The present invention has been made to solve the above problems, and its purpose is to detect the wind direction and wind speed around a building, and to automatically open and close the ventilation window based on the detection result to adjust the wind direction and wind speed. It is intended to provide a natural ventilation device for a building, which can naturally ventilate the interior of the room to an optimum state regardless of the situation.

[0005]

In order to achieve the above object, the present invention relates to a plurality of ventilation windows provided along a peripheral surface of a building under a slab of a building having a polygonal or circular cross section, and the ventilation windows. A shelf-shaped ventilation guide that is arranged along the inner circumference of the building in the lower part of the window and has a partition for each of the ventilation windows, an opening / closing adjustment means provided for each of the ventilation windows, and the periphery of the building. The wind direction and the wind speed detecting means for detecting the wind direction and the wind speed; and means for calculating the opening / closing degree of the opposing ventilation windows based on the wind direction and the wind speed data obtained by the wind direction and wind speed detecting means. The opening / closing adjustment means is driven to adjust the opening / closing of the ventilation window.

[0006]

The ventilation window located on the windward side and the windward side is specified by the wind direction data, and the opening / closing degree of the corresponding ventilation window is determined according to the wind speed data. The wind blown into the building from the windward side passes through the building and is discharged from the ventilation window on the leeward side.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. 1 and 2 show a building to which the present invention is applied. This building has a multi-story plan in which a substantially circular polygonal outer wall 2 is formed around a cylindrical center core 1.

The center core 1 constitutes a utility space such as a staircase, an elevator, a toilet, and a washroom, and the space on each floor surrounding the utility space is a general living room. A large number of ventilation windows 4 are arranged along the peripheral surface of the outer wall 2 below the slab 3 on each floor.

A doughnut-shaped shelf-shaped ventilation guide 5 is fixedly arranged on the inner periphery of the building below the ventilation window 4. Partition plates 6 are radially arranged on the upper part of the ventilation guide 5 for each ventilation window 4 to partition the ventilation window 4 in the circumferential direction, and the inside of each ventilation window 4 is directed to the center core 1.

If the upper surface of the ventilation guide 5 is a mirror surface, the natural light transmitted through the ventilation window 4 is reflected on the surface of the ventilation guide 5 and is applied to the lower surface of the slab 3. Is obtained.

Each ventilation window 4 has a structure of opening and closing at an arbitrary angle by a motor drive system, and is opened and closed by a control means such as a microcomputer shown in FIG. The control means in the figure includes wind direction detecting means 7, wind speed detecting means 8, outside air temperature detecting means 9, temperature and humidity detecting means 10 for each floor, wind speed detecting means 11, and each of these detecting means. An arithmetic control unit 15 is provided which receives data and data from an air conditioner 12 and a key input device 14 which are separately provided, and which controls the drive of the drive motors M1 to Mn attached to each of the ventilation windows 4. The calculation control unit 15 executes the following control according to each input state as shown in the flowchart of FIG.

In FIG. 4, first, an instruction from the key input device 14 is used to specify whether or not the natural ventilation mode is set. If the natural ventilation mode is not set, it is searched whether or not there is a previously opened place. If there is an open place, a drive command is issued to one of the corresponding motors M1 to Mn to fully close the ventilation window 4 (steps 1 to 3).

In the case of natural ventilation mode, the data of the respective detecting means 7 to 11 are read, and when the indoor / outdoor temperature difference is equal to or more than the set value, the center direction 1 is inserted by the wind direction detecting means 7. The corresponding opening / closing locations of the ventilation windows 4 on the leeward and leeward sides are calculated (steps 4 to 6).

Next, the air volume corresponding to the air conditioning load in the room is calculated, the opening of the ventilation window 4 corresponding to this air volume is calculated, and the corresponding drive motors M1 to Mn are driven according to the opening ( Steps 7 and 8).

After that, the temperature and humidity in the room and the maximum airflow velocity are monitored, and when the maximum airflow in the room exceeds the set values, step 7 is repeated.
, The ventilation window 4 was corrected to the optimum opening degree, and if it was less than the set value, the outdoor wind direction and wind speed were monitored, and if there was a change in these, a command was issued to close the ventilation window 4 that was opened last time. After that, the operation of returning to step 1 again is repeated (step 9-
13).

When the ventilation window 4 corresponding to the external wind direction is opened according to the above control operation, the wind blown into the building from the windward ventilation window 4 as shown by an arrow in FIGS. 5. Guided by the partition plate 6 toward the center core 1, colliding with the center core 1 at the center of the building while descending, rising while being surrounded by the surrounding space and being discharged from the ventilation window 4 on the leeward side . The opening of the ventilation window 4 is constantly adjusted according to the wind speed outside the building, and the air passes through the room indoors and outdoors at a constant wind speed corresponding to the air conditioning load.

Although the ventilation duct 5 is provided below the ceiling surface 3a in the embodiment, it may be provided behind the ceiling. In this case, the air supply opening may be communicated with the ceiling surface. Also,
In this embodiment, the building is formed on the polygonal outer wall 2 having a substantially circular shape. However, the number of sides may be reduced to form a triangle, or the number of sides may be increased to a polygon or a circle.

[0018]

As described above in detail with reference to the embodiments, in the natural ventilation system for a building according to the present invention, the ventilation windows located on the windward side and the leeward side are specified by the wind direction data, and according to the wind speed data. Since the degree of opening / closing of the corresponding ventilation window is determined and the corresponding window automatically opens / closes at a predetermined opening, there is no need for the manual operation of opening / closing due to natural ventilation, and the wind speed is set to an optimum value. Also, due to the structure of the building,
The wind that blows into the building from the windward side passes through the building and is discharged from the ventilation windows on the leeward side, so the ventilation wind can spread throughout the interior space of the building and prevent unevenness depending on the location. Moreover, wind damage to the surrounding area can be suppressed.
